Recently, my computers memory consumption has gone up from 25% idle to 33-34% idle. It usually goes up after about 2 hours of being turned on. When the memory is at 33-34% one of the svchost process's (note there are 3) is very high 64,000-73,000 k of memory is being used by it (when usually it is at 40,000- 50,000). I have scanned my computer for viruses and found none. My computer is an Inspiron E1505,2GB ram, Windows Vista Home Premium, 1.83GHZ centrino duo. What is causing it to be so high & will it return to normal soon?
